HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 255,335, dated March21, 1882.

Application filed October 28, 1881. (No model.)

To all whom it may concern:

Be it known that I, EDWARD A. Rrx, ot the city and county of SanFrancisco, State of California, have invented an Improved Hose-Goupling; and I hereby declare the following to be a full, clear, andexact description thereof.

My invention relates to a-device for secuu ing the ends of flexible hoseto couplings.

My invention consists in eertaindetails of construction, as hereinafterdescribed and speciflcally claimed.

Referring to the accompanying drawings, Figure 1 is a View showing thehose secured to the coupling. Figs. 2, 3, and at show the parts of thecoupling and clamp separated. Fig. 5 is a longitudinal section.

A is-one end or portion of a hose-coupling such as is employed toconnect lengths of hose so as to make a continuous tube. 4 The couplingdevice proper may be of any suitable or convenient form, this portionnot concerning my present invention.

B is an extension or tube having an exterior diameter which will allowit to be inserted into the end of the hose, and it mayhave a slightswell or enlargement, as shown at a, for additional security, and isprovided with the flange I, as shown in Fig. 2. Theinterior opening orbore forms a continuation of the interior of the hose anda continuouspassage therewith.

From the enlarged flange of the coupling two elastic arms,D, extend backparallel with the tube B, and at such a distance from it as will admitthe end of the hose to pass inside of them when it is slipped over thetube B. The said flange J,is provided with a male screw-thread, as shownin Fig. 4, to receive over it the band K, provided with the femalescrew, as shown in Fig. 3. These arms are placed opposite each other,and are of some breadth, and their inner surfaces are made concave, soas to lit the exterior shape of the hose. At their ends they haveextensions E in the form of bands, each of which extends about half-wayaround the hose, and lugs F project from these semi-bands. These lugshave holes formed through them to admit screw-bolts G with nuts, bywhich they may be drawn together, and the bands and arms thus caused toclamp the hose firmly upon the extension-tube 13.

Havingthusdescribed my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The hose-coupling herein described, consisting of the tube B, fittingwithin section A of hose, and provided with a flange, against whichabuts the flange L, in combination with the ring K, the clamp D,provided at one end with amale screw and at the other end with sectionalring E, having fastening-lugs F, and bolts Gr, all constructed andarranged as set forth.

In witness whereof I hereunto set my hand.

EDWARD A. RIX.
